DRAWING-=PAD DEVICE.

Specification of Letters latent.

Patented Apr; 26, 1921.

Application filed August 25, 1920. Serial No. 405,854.

To all whom it may concern Be it known that I, HENRY P. JONES, a citizenof the United States, residing at Buffalo, in the county of Erie andState of New York, have invented certain new and useful Improvements inDrawing-Pad Devices; and I do hereby declare the following to be a full,clear, and exact description of the same, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to figures ofreference marked thereon, which form part of this specification.

Like figures of reference refer to like parts.

This invention relates to drawing pad devices.

One of the objects of this invention is to provide for the use of amechanical, architectural or other sketcher, a manifold pad of tracingor opaque paper for preliminary work, having printed on the margin ofeach sheet a graduated scale, which will enable the sketcher toproportion his figures without the use of a rule, thus saving time.

Another object is to provide a drawing pad which is adapted to the useof a T-square and triangle, having detachable printed strips at themargin of the sheet, which the sketcher removes before filing the sameaway. leaving the body of the sheet of a standard size.

With these and other objects, one embodiment of this invention isillustrated in the drawings, the construction is described, its useexplained and what I claim is set forth.

In the drawings,

Figure 1 is a perspective view of a drawing pad device embodying myinvention.

Fig. 2 is a plan of a detached sheet showing a sketch thereon, ready forfiling, having the graduated marginal strips removed.

In the figures, 1 is a thin drawing board, which may be made of anysuitable wall board or wood or such material as will receive tacks.Under the four corners of the drawing board 1, I preferably providerubber pads 2, which serve, by their friction, to keep the board 1 fromshifting on a table, while being used. Upon the board 1, is tacked. thebacking 3 of the pad4c; the sheets 5 of which pad are glued together atthe top 6. Each sheet 5 has narrow marginal strips 5 and 5" at adjoiningedges, which are separable from the body of the sheet 5 at theperforated lines 7 and are divided preferably into inches, halves,quarters, and eighths, while I also provide an intermediate subdivisionof one-sixth inch each, indicated by the rows of dots D, the spacing ofwhich is the same as typewritten matter.

In using this pad device, the T-square 8 and triangle 9 serve in theordinary way as guides in drawing, while the graduations aid indimensioning ofi the lines of the figure which is drawn upon the body ofthe sheet 5. After the drawing or sketch is complete, the marginalstrips 5 and 5 are removed from the body of the sheet 5, leaving thesheet of some regular size, such as 8% X 11, convenient for filing away,as is shown in Fig. 2, the edges '7 being those from which the marginalstrips 5 and 5 are torn.

Such a pad is also serviceable for tabulating and such vertical lines as10, 11 and 12, may be spaced in accordance with the subdivisions of thestrip 5 while horizontal lines as 13, may be drawn preferably spacedone-sixth of an inch apart, using the dots D for guiding the spacing ofsuch lines, as may be required for writing on the pad. 14, is a sampledesign sketched upon the sheet 5.

With the detachable strips 5 and 5 subdivided into convenient divisionsprinted thereon for guides, and the pad being of such construction inconnection with the drawing board of the size, as to lend itself iencealways, a fresh sheet of paper ready for a new sketch without thenecessity of each time tacking a separate sheet to the drawing boardbefore he begins, at the same time, dispensing with thumb tacks.

After one drawing pad is used up, it can be removed and a fresh drawingpad tacked upon the board 1, or while the drawing pad is thick enough togive support to the T- square, it can be used without mounting it uponthe board 1.

Details of the embodiment of my invention herein shown and described,may be changed without departing from the spirit and scope thereof, Itherefore do not wish to be confined to this one embodiment, hence Iclaim,

1. A drawing pad comprising a plurality of sheets cut to rectangularshape and glued together at one edge thereof and a marginal strip toeach sheet divided from the same by a weakened line whereby said stripmay be easily torn from the body of the sheet, and a series of equallyspaced divisions marked lengthwise on said strip.

2. A drawing pad comprising a plurality of similarly sized and shapedsheets, cut to a rectangle, and glued together at one end of the sheetsand two adjoining marginal strips on each sheet, subdivided by equallyspaced marks the length of the strip, each strip being separable fromthe body of the sheet on a weakened line.

'3. In a drawing device the combination of a drawing pad comprising aplurality of similarly sized and shaped sheets of paper or the like, cuttoa rectangle, and glued together at one end of the sheets, and twoadjoining marginal strips on each sheet, subdivided by equally spacedmarks, the length of the strip, each strip being separable from the bodyof the sheet on a serrated line,

and a board of the same size and shape as Eaidd sheet, to which said padis releasably HENRY P. JONES.
